Abstract A surface tension device for use in a liquid acquisition reservoir and comprised of a porous membrane that maintains a separation between gas and liquid and thereby isolates accummulated gas from the liquid acquired and subsequently delivered free of entrained gases; and comprised of a porous baffle held spaced from the vessel wall and establishing a liquid acquisition chamber separated from the liquid a storage chamber and wherein pure liquid is acquired and subsequently withdrawn through an opening; the baffle being characterized by its ski-shape as it is installed within the confines of a cylindrical storage vessel with hemispherical ends and to the end that substantially complete acquisition of the available liquid from the resevoir is assured.
A device for acquisition of gas-free liquid from a closed storage vessel having an acquisition opening in one side portion thereof, and including; a collapsible imperforate membrane coextensively lining the interior of the vessel, and a porous surface tension partition juxtapositioned in closely spaced relation to and with its periphery sealed with the membrane and disposed over said side portion of the vessel and the acquisition opening therein and defining a liquid acquisition chamber in open communication with said liquid acquisition opening and separate from a liquid storage chamber within the membrane.
